Students using the scientific method, study bacteria as a covering surface of the earth in many forms. They discover that not all bacteria is bad and introduce the topic of antibiotic resistance. Science Fair expectations are addressed.

Middle schoolers explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth...

Students practice writing research proposals to test the color fastness of a dye once it has been exposed to a t-shirt. Each proposal needs details of experimental design, length of treatment, and means of cleaning the shirt. All...

Seeing how seeds grow into plants is such an enjoyable for students! They plant lima bean seeds and take pictures to record the growth of their plants. Students write in a journal to describe their daily observations of their plants, and...

It's often confusing which word should be used to complete a sentence. Although this worksheet's title insinuates that idioms will be discussed, the practice section is just about using words like to, who, with, as, and that correctly....

Students research Brazil's history and note the changes that take place over time in Brazil's history. They analyze reasons for changes in Brazil's history and compare and contrast Brazil's history with that of the United States in...

Students develop a descriptive and informative brochure for a National Park. They focus on the history and geology of the park, environmental concerns, and visitor actions that could eliminate the environmental concerns.

Students research inventions that have been created. In this historical technology lesson, students read the Harcourt Brace social studies textbook and discuss how inventors used graphs to display data. Students create a table to write...

Students explore fascinating world of rainforest, and participate in activities such as adopt-an-acre-of-the- rainforest, adopt-a-rainforest-animal, sequencing, comparing and contrasting, word processing and searching the Internet.

Fourth graders engage in a virtual tour of the state of Florida.

Students read an essay by H.D. Thoreau as analysis of his philosophy on government. In this Thoreau analysis lesson, students work in groups to paraphrase two of Thoreau's criteria for his beliefs about government. Students write a...

Students perform an experiment in order to determine how increasing weight affects the velocity of a truck and use the computer to compile their data.

Fourth graders experiment to determine how overpopulation effects ecosystems specifically plants. In this ecosystem lesson, 4th graders conduct an ecosystems experiment after listening to Claire Daniel's, Ecosystems. They watch a video,...

Students measure the amount of calories in food. In this food energy lesson, students discuss what a calorie is, how our bodies use a calorie, and how many we need. Then, students use a calorimeter to calculate the amount of energy in a...

Fourth graders determine the amount of energy required to melt ice using a calorimeter. They calculate the Molar Heat of Fusion of Ice.

In this energy lesson, students create calorimeters out of soda cans and use them to calculate the amount of energy stored in different types of wood.

Students, in groups, develop their hatcheries, working cooperatively in its design and construction. The lessons begin with the introduction to Artemia as a primary food source of many aquaculture species during their larval stages.

Students explore Bernoulli's principle, how it is related to flight, and the effect of lift, thrust, and drag on flight. They design and develop an experiment that tests for distance traveled by their paper airplane, and record and...

Learners determine the identity of the three classes of levers while explaining how each works. They wait a video clip that shows uses for different types of levers and work as a class to write a KWL chart. Finally, they make a model fo...

Students examine relationships and interactions between different types of water. They experiment with colored water of different temperature and salinity and discuss how the results relate to real ocean currents.

Learners discuss the scientific method and construct their own Mobius Strips. They examine their Mobius Strip, and write observations and a hypothesis on how many strips of paper they have when they cut the strip in half length-wise.

Students role play as paleontologists who make inferences about the weight of dinosaurs. They use models and the density of water to make these inferences.
